ABSTRACT

A new cultivar of  Gaultheria shallon  plant named ‘Gaulsidh12’ that is characterized by its new foliage and stem growth that is red in color, its leaves that are narrow and pointed, and its broadly spreading plant habit.

Botanical classification: Gaultheria shallon.

Cultivar designation: ‘Gaulsidh12’.

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to a Canadian Plant Breeder's RightsApplication No. 21-10463 filed on Apr. 15, 2021, under 35 U.S.C. 119(f),the entire contents of which is incorporated by reference herein. Thisapplication is also co-pending with a U.S. Plant Patent Applicationfiled for a plant derived from the same breeding program that isentitled Gaultheria Plant Named ‘Gaulsidh4’ (U.S. Plant patentapplication Ser. No. 17/701,023).

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofGaultheria shallon, botanically known as Gaultheria shallon ‘Gaulsidh12’and is hereinafter referred to by its cultivar name ‘Gaulsidh12’.

‘Gaulsidh12’ was discovered by the Inventor as a chance seedling thatwas growing in a container in Mission, B.C., Canada in spring of 2017.The containers had been planted with seed derived from unnamed andunpatented plants of Gaultheria shallon. The exact parents are unknown.

Asexual propagation of the new cultivar was first accomplished by tissueculture using meristemac tissue under the direction of the Inventor inMission, B.C., Canada in spring of 2018. Asexual propagation of the newcultivar by tissue culture has shown that the unique features are stableand reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent thecharacteristics of the new cultivar. These attributes in combinationdistinguish ‘Gaulsidh12’ as a new and unique cultivar of Gaultheria.

-   -   1. ‘Gaulsidh12’ exhibits new foliage and stem growth that is red        in color.    -   2. ‘Gaulsidh12’ exhibits leaves that are narrow and pointed.    -   3. ‘Gaulsidh12’ exhibits a broadly spreading plant habit.

‘Gaulsidh12’ can be most closely compared to typical plants ofGaultheria shallon and ‘Gaulsidh4’. Both are similar to ‘Gaulsidh12’ inflower color. Typical plants of Gaultheria shallon differ from‘Gaulsidh12’ in having leaves that are ovate to almost round in shapeand in having new growth that is green in color. ‘Gaulsidh4’ differsfrom ‘Gaulsidh12’ in having a very compact plant habit, a smaller plantsize, leaves that are smaller in size and more rounded in shape, newgrowth that is green in color, and in producing more flowers.
